X-NUCLEO-NFC01A1 Dynamic NFC Tag Expansion Board Firmware Package
Introduction
This firmware package includes Components Device Drivers, Board Support Package and example applications for STMicroelectronics X-NUCLEO-NFC01A1 Dynamic NFC Tag Expansion Board based on M24SR.
Example Application
The application provides a simple example of asynchronous access to the X-NUCLEO-NFC01A1 Dynamic NFC Tag Expansion Board. The program writes a URI link to the M24SR dynamic tag using the asynchronous programming model. The URI can then be retrieved from an NFC enabled smartphone/tablet.
A simpler example providing synchronous access to the tag is also available.
